Webservice Asynchcallabck

Question

Gurus,

We are developing a web application, where in users can upload zip file that can have 1000s of records, which we parse and make request to specific webservice for response... till 1000 records we are able to get response... we are using Aynchcallback method to handle the response returned by service... but when number of request increase we are not getting response... we get error... Need advice on How many request we can send aynchronusly... is it required to maintain a pool for handling response...

basically in the callback method we get the XML response, parse it and store it in DB... Need guidance on the same...

Answer 2

OutOfMemoryException or worker process being recycled I think.

The default requestLengthDiskThreshold is 256kb per session, so 1000 request means 256MB is spent on solely storing the file being upload on the way. You may want to check what is the setting of memory limits in the application pool settings. (and machine.config and web.config)

Hi Sarran,

You are more likely to get more efficient responses to ASP.NET issues at http://forums.asp.net where you can contact ASP.NET experts.

Thanks for your understanding.
